Self‐Amplified Drug Delivery with Light‐Inducible Nanocargoes to Enhance Cancer Immunotherapy

Feng, Bing, Hou, Bo, Xu, Zhiai, Saeed, Madiha, Yu, Haijun, Li, Yaping·2019·Advanced Materials

Abstract

Chemoimmunotherapy by systemic administration of individual regimens suffers from inconsistent pharmacokinetics profiles, low tumor specificity, and severe side effects. Despite promising nanoparticle‐based codelivery approaches in therapeutics, the pathophysiological barriers of solid tumors are a hurdle for tumor accumulation and deep penetration of the drug‐loaded nanoparticles. A light‐inducible nanocargo (LINC) for immunotherapy is reported. LINC is composed of a reduction‐responsive heterodimer of photosensitizer pheophorbide A (PPa) and indoleamine 2,3‐dioxygenase 1 (IDO‐1) inhibitor, i.e., NLG919, and a light‐activatable prodrug of oxaliplatin (OXA). LINC administrated through intravenous injection is passively accumulated at the tumor site to generate near‐infrared (NIR) fluorescence signal. Under fluorescence imaging guidance, the first‐wave of NIR laser irradiation induce reactive oxygen species (ROS) generation, trigger cleavage of the polyethylene glycol (PEG) corona, and thus promote tumor retention and deep penetration of LINC. When exposed to the second‐wave NIR laser illumination, LINC efficiently elicits the immune response and promotes intratumoral infiltration of cytotoxic T lymphocytes (CTLs). Furthermore, NLG919 delivered by LINC reverses the immunosuppressive tumor microenvironment by suppressing IDO‐1 activity. Chemoimmunotherapy with LINC inhibit the tumor growth, lung metastasis, and tumor recurrence. The light‐inducible self‐amplification strategy for improved drug delivery and immunotherapy shows potential.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
